Thanks for all the input. Fluff-wise..., these HAVE to be Salamanders.
The reason is that I am thinking of painting up another rhino for Games Day next year and I want to make sure that I set the model apart from all the others but not so much that it doesn't fit the fluff (I've been heavily criticized for that in my past entries) Therefore, I wanted to experiment with the greens but still make them easily identifiable. So what you guys say is VERY important. If it doesn't work- I'm not doing it.
